Abstract

This specification covers the highest quality of round chromium-vanadium alloy steel wires for manufacture of valve springs and other springs with high-fatigue properties under moderately elevated temperatures. The wires shall be annealed, cold-drawn, or oil-tempered. The material shall conform to specified carbon, manganese, phosphorus, sulfur, silicon, chromium, and vanadium contents. Guidelines for mechanical testing are given. Values for tensile requirements are provided. Material decarburization shall be examined. Attention is also given to workmanship, finish, and appearance of the product, and as well as its inspection, rejection, rehearing, and certification. Packaging, marking, and loading for shipment is also described.

Scope

1.1 This specification covers the highest quality of round chromium-vanadium alloy steel valve spring wire, uniform in quality and temper, intended for the manufacture of valve springs and other springs requiring high-fatigue properties when used at moderately elevated temperatures. This wire shall be either in the annealed and cold-drawn or oil-tempered condition as specified by the purchaser.

1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. Within the text, the inch-pound units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independent of the other.
